Most well known for their complex vocalizations, humpbacks are also very acrobatic, often breaching, tail-lobbing, pectoral slapping and lunge-feeding to the delight of observers. Humpback whales are found in oceans worldwide, where they breed and calve in the warm tropical seas, then migrate to feed in the colder northern or southern oceans. Mid-sized baleen whales, humpbacks average 12-15 meters in length and weigh 30-45 tonnes.
In 1994, a single humpback whale was sighted once in Clayoquot Sound. Sighting rose steadily every year, until present when throughout the summer months, humpbacks are sighted almost daily. One day, last August there were an estimated 45 whales feeding within a 3 km radius.
